Course Description

Additive Manufacturing deals with aspects of additive, subtractive, and joining processes to form three-dimensional parts with applications ranging from prototyping to production. Additive manufacturing processes directly from computer-aided-design (CAD) models. In this course, students will learn about a variety of AM and other manufacturing technologies, their advantages and disadvantages for producing both prototypes and functional production quality parts. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

  1. Demonstrate an understanding of several AM 3D printing processes to produce a 3D part.

Course Objectives

  • 1. Understand several AM processes SLA, FDM, SLS, DMLS, Polyjet Printing, SLM, Bio Printing, LENS, and EBM.
  • 2. Set up and run a FDM machine and a Concept laser DMLS using 316L Stainless Steel material.
  • 3. Remove support materials from both FDM and DMLS.
  • 4. Methods of finishing prototypes.
  • 5. Understand how to use AM systems to create injection molds and tools to create models from silicones and urathanes.
